This is a mobile home park that went through Hurricane Sally.  The park is operated as a business and takes the QBI deduction.  Some of the mobile homes in the park suffered damages to the roofs, siding, underpinning, etc., but the homes are not a total loss.  In some cases a separate asset is established when new roofs were added.  So taking the new roof as an example, the owner will be making roof repairs, but the entire roof will not need to be replaced.  Does the original asset need to stay on the books?  Is the original asset adjusted for the costs needed to repair the roof? Or is a new asset added for costs that haven't yet occurred since the owner will be making repairs over time.  However, Casualty Losses must be reported in the year they occur.  Right now, I'm just leaving the original asset as it is, with no adjustments, and taking the Contractor estimates and owner's estimates for repairs as the Casualty loss.  Does this sound correct?
